使用IDEA實現SSM整合(Maven+Spring+Mybatis+SpringMvc)

我是阿福，公衆號「阿福聊編程」做者，一個在後端技術路上摸盤滾打的程序員，在進階的路上，共勉！

文章已收錄在 JavaSharing 中，包含Java技術文章，面試指南，資源分享。

本文是基於Maven工程實現SSM整合，主要是經過XML實現三大框架的整合，可能有的小夥伴會說XML早就過期了，如今人們都使用註解開發，可是不是這麼認爲，我我的以爲你XML 整合會了，註解能不會嗎？ 開幹！！！！

SSM整合整體思路

Spring和MyBatis整合

配置數據源

在配置文件spring-persist-mybatis.xml，分爲兩步：加載外部的屬性文件，配置數據源

<!--加載外部的屬性文件-->
    <context:property-placeholder location="classpath:db.properties"></context:property-placeholder>
    <!--配置數據源-->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">

        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">

        <!--裝配數據源-->
